“…Still, there were 13 Alexandrium species detected that were not previously known to be present in Australian marine waters, including A. andersonii, A. cohorticula, A. hiranoi, A. insuetum, A. leei, A. mediterraneum, Group II, A. monilatum, A. pohangense, A. satoanum, A. tamarense Group III, A. tamiyavanichii, A. tamutum and A. taylorii. Another HAB species not previously reported in Australian waters but detected at low relative abundances here is Karenia brevis [58]. These novel findings clearly highlight the usefulness of the ability to be able to detect rare and less abundant taxa utilising eDNA sampling and HTS genotyping.…”

“…In contrast, one of the least abundant genera, Alexandrium (0.05-0.1%), was comprised of 17 species from the possible 23 contained in the DinoREF database, however all 23 Alexandrium species were identified in the whole assemblages (Additional file 1: Table S4 and S5). Of the species identified here, 11 are previously reported from Australian waters [16,57,58]. There are also many reports of Alexandrium catenella, Group IV, in Australian waters, a known HAB associated with paralytic shellfish poisoning; however, this species is not contained in the DinoREF database.…”

“…Aquacultured finfish mortalities caused by the taxonomically unrelated microalgal genera Chattonella, Pseudochattonella, Heterosigma, Karenia, Karlodinium, Margalefidinium (Cochlodinium) and Prymnesium/ Chrysochromulina globally account for much greater economic damage than HABs contaminating seafood 39 . While most shellfish toxins have now been well characterised and are effectively monitored and regulated, finfish held captive in intensive aquaculture operations continue to be vulnerable to HABs (USD71M loss in Japan in 1972, USD70M in Korea in 1995, USD290M in China in 2012, USD100M in Norway in 2019 [19][20][21][22][23][24][25][26][27][28][29][30][31][32] ), even though the causative ichthyotoxins usually are of no human health significance. The 2016 Chilean salmon mortality that caused a record USD800M loss led to major social unrest 40 .…”

“…Each region was assigned a regional editorial team tasked with collating information on HAB species occurrences and impacts, with the data and interpretations published in a special issue of the journal Harmful Algae (vol. 102, February 2021) [19][20][21][22][23][24][25][26][27][28][29][30] . As more sampling could lead to more observations of HABs, we estimated sampling effort using OBIS, the most comprehensive dataset on marine species records, as a proxy for sampling effort.…”

“…The regional appearance and increase of other HAB phenomena have in contrast been attributed to climate-driven range expansion; exemplified by the dinoflagellate Noctiluca scintillans. Highly visible red tides and bioluminescent spectacles caused by Noctiluca were first documented in Australia from Sydney Harbour in 1860 (Bennett, 1860), have been more frequently reported since the 1990s, and even caused temporary closure of popular Sydney tourist beaches (Hallegraeff et al, 2020). Amongst the causes of N. scintillans blooms are eutrophication, upwelling and ocean circulation (Dela Cruz et al, 2002, 2003).…”
